The REF3140AQDBZRQ1 is a voltage reference integrated circuit that falls under the broader category of PMIC-Voltage Reference products. It is a precision series voltage reference with a temperature coefficient of 0.5 ppms/C and a supply current draw of just 2.75 μA in the operating temperature range of -40° to 125°C. This integrated circuit provides a stable output voltage of 3.3V over a wide range of temperature and supply variations, making it an ideal choice for high-precision and low-power operations. The device is designed to be used mainly in industrial, automotive, communications and instrumentation applications, as well as in various medical and military systems.

The basic operating principle of the REF3140AQDBZRQ1 is based on a current source circuit. A current source is used to shift the input voltage to the output voltage. The input voltage is adjusted by an external resistor, and the output voltage is adjusted by an external capacitor. The output voltage is then regulated by a precision band-gap reference circuit, which maintains the output voltage at a precise level regardless of the input voltage. This enables the device to provide superior stability and accuracy, even in environments where the input voltage can fluctuate significantly.

The REF3140AQDBZRQ1 is also designed to be very robust and reliable. It features an internal amplifier with a low-distortion architecture, as well as noise rejection circuitry. This allows the device to provide clean and stable output signals, even in electrically noisy environment. It also incorporates a temperature compensation feature, which allows the output voltage to stay stable over a wide range of ambient temperatures. This temperature compensation feature also helps to extend the operating life of the device.

In addition to its superior performance, the REF3140AQDBZRQ1 also offers several other benefits. The device is designed to operate from a wide input voltage range of 3.0 to 30V, making it ideal for a variety of applications. It also features reverse-bias protection, which helps to protect the device from being damaged due to a reversed polarity voltage input. The device also features a maximum sink current of 300 mA, allowing it to supply more power than most competing products.

All in all, the REF3140AQDBZRQ1 is a reliable, high-performance integrated circuit for industrial, automotive, communications, instrumentation and medical applications. Its low supply current draw and wide operating temperature range make it an ideal choice for low-power operations. Its temperature compensation feature helps to extend the device’s operating life, and its reverse-bias protection offers extra protection from damage. Finally, its extra large maximum sink current of 300 mA makes it suitable for a wide range of applications.
